Surfing the net I stumbled upon this site – http://macaulaylibrary.org/
What’s so special here? Well, they claim (and I believe them), to have recordings – audio and video, of over 150.000 species of bird, mammals, reptiles, fish and so on. Ok! Sooo? I always asked myself about sounds that various animals and bird do, or how really look some. It’s an instructive site, a resource for some future to be biologist and also something unique.
